An airbag inflator that includes a pyrotechnic material capable of producing a quantity of gas during deployment. The inflator also includes a filter. The filter may be an expanded metal filter that is wrapped about the pyrotechnic material. When this filter is wrapped about the pyrotechnic material, the filter forms a plurality of layers having holes that are a different size. This filter also includes a first set of barriers and a second set of barriers that are positioned exterior of the first set of barriers, the second set of barriers being offset from the first set of barriers. Gas passing through the filter will encounter the first set of barriers, be re-directed, encounter the second set of barriers, be re-directed, and then flow out of the filter.

A binder matrix suitable for use in a gas generant composition, a gas generant composition including the binder matrix, and a related method of igniting such a gas generant composition are provided. The binder matrix includes a non-energetic binder material and dimethyl malonate non-energetic plasticizer and has a softening temperature above at least about 125&deg; C. A gas generant composition including the binder matrix includes a non-energetic binder material such as cellulose acetate, dimethyl malonate non-energetic plasticizer, a fuel such as a nitramine fuel such as RDX, HMX or a combination thereof, and a stabilizer such as N-methyl-p-nitroaniline.

Binder matrix for gas generants and related compositions and methods

A gas generant material body in the form of a tablet having a triangular cross section and associated methods of gas generation are provided.
